War seemed like something that was going to happen eventually in this series, but wow, they really went out of their way just to show how bad war really is in this.

Gentoku seems to now trying to be an ally for Sento and Banjo even though the latter two really don't want to work for him, pretty much a forced situation. I'm guessing given how the conflict is now that he will now be fighting alongside the other two as Kamen Rider Rogue when that rider debuts.

Seems Katsuragi intentionally left the driver incomplete because he knew it would cause war. This is a really cool way of tying in why he wanted to leave Faust. Clearly the "Devil's Scientist" was actually a good guy all along who effectively got backstabbed by the people he was working alongside (namely Soichi and Gentoku), which works well as it suggests his personality never really changed when he became Sento.

Really the only mysteries he have left are all related to the Box and Soichi. How did Soichi get all of these abilities? What is his ultimate goal? Is the box the real villain? Will destroying Pandora Box be the means by which all this conflict is resolved? I get the impression we probably won't find out until the back half and the series is going to focus for a bit on trying to resolve how to stop the war. If I had to guess, Sento's next big upgrade, the Hazard Trigger, or the subsequent RabbitRabbit and TankTank upgrades will be the moment this war arc ends and another arc begins. Either that or war esculates to a new level altogether and Seito is brought into the conflict making a three way war.

I wouldn't say that. He was like many of the "intellectual" class with vainglorious dreams and disregard or contempt for those who might suffer. He had a Road to Damascus moment at the end and tried to quit Faust, only to be foiled.
